Mueller Streamline PDWV4851-4IN Closet Flange 4 Inches

Product Description

The MUELLER STREAMLINE PDWV4851-4IN is a 4-inch closet flange designed to connect a toilet to the drain-waste-vent (DWV) rough-in pipe below the finished floor. This fitting anchors the toilet base, provides the wax ring seating surface, and ties the fixture to the drain stack. It is installed during rough-in by licensed plumbers on new construction and remodel projects alike. The 4-inch nominal size matches standard residential toilet drain configurations.

This closet flange is suited for residential and light commercial plumbing applications where a 4-inch DWV connection is required. It is used in bathroom rough-in situations where the drain pipe terminates at or near the finished floor level, requiring a stable, code-compliant flange to support the toilet fixture and maintain a sealed connection to the drain system.

Key Features

• 4-inch nominal size matches standard residential toilet drain rough-in
• Designed to anchor toilet base and provide wax ring seating surface
• Compatible with DWV pipe systems at floor level
• OEM-style replacement or new-construction fitting

Compatibility

Designed as an OEM-style replacement or new-installation closet flange for residential and light commercial DWV systems using 4-inch drain pipe.

Installation Notes

Installation is performed by a licensed plumber in accordance with the International Plumbing Code (IPC) and local amendments. Shut off the water supply and ensure the drain line is clear before beginning work. The flange should be set at the correct height relative to the finished floor surface to ensure a proper wax ring seal. Do not overtighten toilet anchor bolts, as this can crack the flange collar.
